Description

Technical Field

[0001] This utility model belongs to the field of coil welding technology, and in particular relates to an electromagnetic pulse welding device for coil welding. Background Technology

[0002] Magnesium and aluminum metal plates can be welded using coil electromagnetic pulse welding. From the welding principle perspective, the interaction between this eddy current and the magnetic field generated by the external coil produces a huge electromagnetic force on the metal plates. This electromagnetic force can cause the magnesium and aluminum metal plates to collide rapidly in a very short time, with collision speeds reaching hundreds of meters per second. Such high speeds can generate extremely high pressure and temperature on the contact surfaces of the metal plates. On the one hand, the high pressure can effectively remove the oxide film and impurities on the metal surface, allowing the clean metal surfaces to come into contact with each other. On the other hand, although the locally generated high temperature will not melt the entire metal, it is enough to give the atoms on the contact surfaces sufficient energy, thereby achieving interatomic diffusion and bonding, forming a strong weld joint.

[0003] When welding magnesium and aluminum metal plates, E-type coils are generally used to complete the welding work. However, existing electromagnetic pulse welding devices have a problem: it is difficult to clamp and fix the E-type coil, which can have an adverse effect on the welding process.

[0032] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0033] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Please see Figures 1 to 6 This utility model provides an electromagnetic pulse welding device for coil welding, including a processing table 1, with a support member installed at the bottom of the processing table 1; a first slide rail 2 is provided on the upper side of the processing table 1, and two first sliders 3 are slidably connected in the first slide rail 2, with a coil 4 installed on the first slider 3; a clamping assembly that contacts the coil 4 is installed on the processing table 1, and an aluminum alloy plate 5 and a magnesium alloy plate 6 are installed on the clamping assembly; the aluminum alloy plate 5 is located below the coil 4, and a pad 7 is installed between the aluminum alloy plate 5 and the magnesium alloy plate 6.

[0035] Using the above scheme: In the process of welding magnesium alloy plate 6 and aluminum alloy plate 5, the operator first unfolds the support to support the processing table 1, then inserts the first slider 3 into the first slide rail 2 and pushes it to the preset position. At this time, the clamping assembly is used to clamp the coil 4 on both sides to fix the coil 4. Then, the magnesium alloy plate 6 and aluminum alloy plate 5 are placed on the clamping assembly, and the pad 7 is placed between the magnesium alloy plate 6 and aluminum alloy plate 5. After placement, the coil 4 is energized, and the current generates a magnetic field through the coil 4, causing the magnesium alloy plate 6 and aluminum alloy plate 5 to collide under the action of the magnetic field, thereby achieving welding.

[0036] Furthermore, the clamping assembly includes two rubber clamping plates 8 slidably connected to the processing table 1; one side of each rubber clamping plate 8 is attached to the bottom of the coil 4; and multiple spring plates 9 are installed inside the rubber clamping plate 8.

[0037] Furthermore, the clamping assembly also includes a first support plate 10 mounted on the rubber clamping plate; the aluminum alloy plate 5 and the magnesium alloy plate 6 are located inside the first support plate 10, and a first fixing plate 11 is fixedly connected to the back of the rubber clamping plate 8; a first spring 12 is installed between the first fixing plate 11 and the rubber clamping plate 8.

[0038] Furthermore, a sliding rod 13 is fixedly connected to one side of the rubber clamping plate 8; one end of the sliding rod 13 passes through the processing table 1, and a plurality of tension springs 14 are fixedly connected between the sliding rod 13 and the processing table 1; an insert plate 16 and a limiting plate 15 are installed on the back of the processing table 1, the limiting plate 15 is rotatably connected to the processing table 1, and one side of the limiting plate 15 is attached to the first slider 3; one side of the limiting plate 15 is located on the insert plate 16.

[0039] The above scheme is adopted as follows: In use, the first slider 3 is installed into the first slide rail 2 by the operator, and the limiting plate 15 is flipped into the insert plate 16. One side of the limiting plate 15 is attached to the first slider 3, thereby limiting the first slider 3 and preventing it from moving in the first slide rail 2. Then, the sliding rod 13 is moved in the preset direction by the tension spring 14, which in turn drives the rubber clamping plate 8 to move to the preset position on the processing table 1. At this time, the rubber clamping plate 8 will be attached to the coil 4, thereby clamping the coil 4. Then, the aluminum alloy plate 5 and the magnesium alloy plate 6 are placed on the first support plate 10. After being energized, the coil 4 generates a magnetic field, causing the aluminum alloy plate 5 and the magnesium alloy plate 6 to collide. During the collision, the first support plate 10 will vibrate, while the spring plate 9 and the first spring 12 play a buffering role. By buffering the vibration of the first support plate 10 through the spring plate 9 and the first spring 12, the vibration generated by the collision of the metal plates is reduced.

[0040] It should be noted that the contact area between the first support plate 10 and the aluminum alloy plate 5 and magnesium alloy plate 6 is made of rubber material.

[0041] Furthermore, the support includes a bearing frame 17 fixedly connected to the processing table 1, and a first support tube 18 is rotatably connected inside the bearing frame 17.

[0042] Furthermore, the support member also includes a threaded rod 19 that is threadedly connected to the first support tube 18; one end of the threaded rod 19 is fixedly connected to a washer 20.

[0043] Furthermore, a limiting piece 21 is fixedly connected to the side of the first support tube 18 away from the gasket 20; both the limiting piece 21 and the bearing frame 17 are provided with threaded holes 22, and bolts 23 are threadedly connected to the threaded holes 22.

[0044] Using the above scheme: When it is necessary to support the processing table 1, the operator operates the first support tube 18 to rotate inside the bearing frame 17, so that it is adjusted from a horizontal position to a vertical position. Then, the support height of the processing table 1 is adjusted by rotating the threaded rod 19 until the required height is reached. At this time, the operator screws the bolt 23 into the threaded hole 22 of the limiting plate 21 and the first support plate 10 to fix the position of the shim 20.

[0045] The working principle of this utility model:

[0046] During the welding process of magnesium alloy plate 6 and aluminum alloy plate 5, the operator manipulates the first support tube 18 to rotate within the support frame 17, adjusting it from a horizontal to a vertical position. Then, the support height of the processing table 1 is adjusted by rotating the threaded rod 19 until the required height is reached, at which point the shim 20 contacts the ground. The operator then screws the bolt 23 into the threaded holes 22 of the limiting plate 21 and the first support plate 10 to fix the position of the shim 20. Next, the first slider 3 is inserted into the first slide rail 2 and pushed to the preset position. The limiting plate 15 is then rotated into the insert plate 16, with one side of the limiting plate 15 adhering to the first slider 3, thereby limiting the first slider 3 and preventing... It moves in the first slide rail 2, and then the sliding rod 13 is moved in a preset direction by the tension spring 14, which in turn drives the rubber clamping plate 8 to move to the preset position on the processing table 1. At this time, the rubber clamping plate 8 will adhere to the coil 4, thereby clamping the coil 4. Then, the aluminum alloy plate 5 and the magnesium alloy plate 6 are placed on the first support plate 10. After being energized, the coil 4 generates a magnetic field, causing the aluminum alloy plate 5 and the magnesium alloy plate 6 to collide. During the collision, the first support plate 10 will vibrate, while the spring plate 9 and the first spring 12 play a buffering role. By buffering the vibration of the first support plate 10 through the spring plate 9 and the first spring 12, the vibration generated by the collision of the metal plates is reduced.
